Title: Humidification system and air conditioner

IPC: F24F13/02
Filed: 2018-12-19
Abstract: Disclosed in the present invention are a humidification system and an air conditioner. The humidification system comprises a refrigerating circuit, a humidifying water path, and an air supply duct. The refrigerating circuit comprises a compressor, an evaporator, and a first condenser. The humidifying water path comprises a water supply portion, a booster pump and a sprayer, and further comprises a second condenser. The second condenser is connected between the water supply portion and the booster pump, and the second condenser is also connected between the compressor and the first condenser or at a refrigerant outlet end of the first condenser. In the present invention, since high-temperature refrigerant that comes out from the compressor will first traverse the second condenser, when the refrigerant traverses the second condenser, water will exchange heat with the high-temperature refrigerant so that the temperature of the water increases, and the heated water then traverses the sprayer and is sprayed into the air supply duct to form water mist. The water mist is mixed with air in the air supply duct. Since the temperature of the heated water is much higher than the temperature of the air, in the foregoing manner, water droplets in the water mist will quickly evaporate into the air to increase the humidity of the air, which thereby improves the efficiency and effect of humidification.
